El Yunque is the only rainforest in the U.S. National Forest System. Comprised of some 240 different species of trees, it is actually a series of forests, each one determined by its altitude.

More than 100 billion gallons of precipitation fall each year which creates the jungle-like ambience of lush foliage, sparkling leaves, shining wet rocks, and shadowy paths occasionally pierced by sunlight.

It is here where you will hear the the noisy, ubiquitous tree frog, el coqu?. No one really knows how many species there are. This little tree frog is very elusive, but you?ll hear them. This is also home to the endangered Puerto Rican parrot.

The best way to see the forest is on foot. You can also appreciate it during a slow drive up and down the mountain. Exploring can be done on your own or take a guided tour.
